Dear Jonathan,
Getting back to Trac 99. I prefer Martin's suggestion here. Are you happy with that? Cheers, Roy. I am retiring on 31/05/2018 but will continue to be active through an Emeritus Fellowship using this e-mail address. ________________________________ From: Martin Juckes - UKRI STFC <martin.juc...@stfc.ac.uk> Sent: 02 May 2018 08:47 To: cf-metadata@cgd.ucar.edu; j.m.greg...@reading.ac.uk; Lowry, Roy K. Subject: Re: [CF-metadata] Standard Names to support Trac ticket 99 Dear Roy, Jonathan, I understand the cause of Jonathan's concern: wikipedia suggests a broader interpretation of "taxon" which would be consistent with using the word to refer to the organisms from a biological taxon, but the Encyclopedia Britannica has a narrower and perhaps more scientifically precise definition in which "taxon" refers to the name, not the organisms matching the name (https://www.britannica.com/science/taxon ). The article uses the phrase "taxonomic category" which could be used as an alternative to Jonathan's suggestion: mass_concentration_of_taxonomic_category_expressed_as_carbon_in_sea_water regards, Martin ________________________________ From: CF-metadata <cf-metadata-boun...@cgd.ucar.edu> on behalf of Jonathan Gregory <j.m.greg...@reading.ac.uk> Sent: 01 May 2018 17:08 To: cf-metadata@cgd.ucar.edu Subject: Re: [CF-metadata] Standard Names to support Trac ticket 99 Dear Roy I agree that the confusion is unlikely. Maybe I shouldn't have given that example, because it's distracting. My discomfort is just that "taxon" doesn't mean "organisms" but "name of type of organisms" e.g. in mass_concentration_of_biological_taxon_expressed_as_carbon_in_sea_water you can substitute your proposed definition of taxon, to get mass_concentration_of_name_identifying_an_organism_as_belonging_to_a_unit_of_classification_expressed_as_carbon_in_sea_water I think you mean mass_concentration_of_organisms_from_biological_taxon_expressed_as_carbon_in_sea_water That's a bit longer, but feels more comfortable to me.
